Who Moved My Buy Button?

You probably heard about the recent stink between Amazon and Macmillan, yes? Amazon didn't like the deal Macmillan was making with Apple over the forthcoming iPad so they made all links to purchase their books inactive on Amazon.
     Yup. Little boys, big toys. Hm.
     Well, here's what's great about our modern day technologies... The Authors Guild has created a website to monitor when Amazon pulls stunts like this. It's called Who Moved My Buy Button? And for all you book creators out there - I suggest you sign on (you don't have to be an AG member). You can list your books (via ISBN) through the site and if your Amazon purchase buttons ever go inactive - you'll receive an email about it. It's still in beta, but I think it's a great idea!
